The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system disedses, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), Sishencong (EX-HN 1) and Taicong (LR 3).

Objective To evaluating the effectiveness of comprehensive measures to control the plague in epidemic areas in Longlin county Guangxi from 2001 to 2010.Methods Original epidemic places was deratised,indicative animals were investigated,and epidemic clues were searched.Cage trapping method was used to capture rat and rat body fleas were collected in the plague epidemic areas.The flea-carrying rates and flea index of rodents were calculated based on the number of fleas collected from caged rodents.The animals were then subjected to etiological and serological tests to determine the plague infection rate.Results A total of 1008 rats were captured and 571 fleas were collected from 2001 to 2010,of which Rattus Flavipestus accounted tor 81.65％(823/1008) and Xenopsylla Cheopis for 64.10％(366/571).The annual average rodents infected with flea and the index of flea were 23.02％ (177/769) and 0.74,respectively.The annual average density of rodents decreased from 3.99％ (859/21 508,before deratised) to 0.96％ (149/15 600,after deratised).The deratization rate was 75.94％.Conclusion The risk of a plague epidemic in Longlin county is reduced after continued comprehensive measures be taken to deal with the disease.

OBJECTIVEDiscuss sterilization effect of B-class pulsation table top vacuum pressure steam sterilizer for dental handpiece.

METHODSAnalysis selection of sterilizer for dental handpiece and sterilization management processes and sterilization effect monitoring, evaluation of monitoring result and effective sterilization method.

RESULTSThe B-class pulsation table top vacuum pressure steam sterilizer to dental handpiece in West China Stomatological Hospital of Sichuan University met the requirement of the chemical and biological monitoring. Its efficiency of sterilization was 100%. The results of aerobic culture, anaerobic culture, B-type hepatitis mark monitoring to sterilized dental handpiece were negative.

CONCLUSIONIt is effective method for dental handpiece sterilization to use B-class pulsation table top vacuum pressure steam sterilizer.

OBJECTIVETo explore the relationship between genetic polymorphisms of glutathione S-transferase (GST) M1, T1 and susceptibility to mountain sickness.

METHODSForty-three soldiers with acute mountain sickness and 80 healthy soldiers matching with sex/age and training under the same condition were divided into case group and control group. A multiple polymerase chain reaction method was used to detect GSTM1 and GSTT1 genes in genomic DNA isolated from peripheral blood cells from both cases and controls.

RESULTSThe frequency of the GSTT1 positive genotype was significantly higher in cases (69.8%) than in controls (42.5%) (P = 0.004, OR = 3.12, 95% CI 1.42 approximately 6.86). The frequency of GSTM1 negative genotype was also higher in cases (72.1%) than in controls (52.5%) (P = 0.03, OR = 2.34, 95% CI 1.05 approximately 5.02). Persons with both GSTM1 and GSTT1 negative genotypes had 5-fold more risk than those with GSTT1 negative and GSTM1 positive genotypes in developing mountain sickness (OR = 5.04, 95% CI: 1.00 approximately 25.3).

CONCLUSIONGenetic polymorphisms of glutathione S-transferase M1, T1 may be the risk factors in the development of mountain sickness.

BACKGROUNDSuperior semicircular canal dehiscence (SSCD) is gradually recognized by otologists in recent years. The patients with SSCD have a syndrome comprising a series of vestibular symptoms and hearing function disorders which can be cured by the operation. In this study, we evaluated the characteristics of patients with SSCD and determined the effectiveness of treating this syndrome by resurfacing the canal via the transmastoid approach using a dumpling structure.

METHODSPatients with SSCD, confirmed by high-resolution computed tomography and hospitalized at Beijing Tongren Hospital between November 2009 and October 2012, were included in the study. All of the patients underwent the unilateral transmastoid approach for resurfacing the canal, and received regular follow-up after surgery. Data from preoperative medical records and postoperative follow-up were comparatively analyzed to evaluate the effect of surgery.

RESULTSIn total, 10 patients and 13 ears (three left ears, four right ears, three bilateral ears) were evaluated in the study, which included 7 men and 3 women. Different symptoms and distinctive manifestations of vestibular evoked myogenic potential were found in these patients. After surgery, 4 patients had complete resolution, 5 had partial resolution, and 1 patient, with bilateral SSCD, had aggravation. None of the patients suffered from serious complications such as sensorineural hearing loss, facial paralysis, cerebrospinal fluid leakage, or intracranial hypertension.

CONCLUSIONSIn patients with unilateral SSCD, resurfacing the canal via the transmastoid approach using a dumpling structure is an effective and safe technique. However, more consideration is needed for patients with bilateral SSCD.

OBJECTIVETo detect aquaporin1 (AQP1) expression in normal human placenta and fetal membranes.

METHODSHuman placenta and fetal membrane specimens were collected from 5 pregnant women with intact membranes undergoing elective cesarean sections at term. Expression and localization of AQP1 was detected by RT-PCR, Western blotting and immunohistochemistry.

RESULTSAQP1 mRNA was detected in the placenta and fetal membranes by RT-PCR, and Western blotting also yielded positive results for the specimens, showing a specific band around 28 kD. Immunohistochemical staining showed AQP1 expression in the vascular endothelial cells and syncytiotrophoblasts of the placenta, epithelial cells of the amnion, and cytotrophoblasts of the chorion.

CONCLUSIONThe presence of AQP1 expression in the placenta and fetal membranes suggest that AQP1 may play an important role in maternal-fetal fluid exchange and amniotic fluid balance.

OBJECTIVETo study the effect of chronic rapid eye movement sleep deprivation on energy metabolism, FT3, FT4 in serum.

METHODSRapid eye movement sleep deprivation of rats were deprived by flower pot, and then the energy metabolism were detected. The FT3, FT4 level in serum was determined by radioimmunoassay kit.

RESULTSRats after sleep deprivation displayed food intake increased from (75.06 +/- 25.37)g/(d x kg) to (122.30 +/- 20.43)g/(d x kg), body weight substantially decreased from (360.89 +/- 43.01) g to (295.97 +/- 37.95) g, body temperature from (37.62 +/- 1.12) degrees C up to the first (39.00 +/- 0.87) degrees C and then reduced to (37.72 +/- 0.84) degrees C, the basal metabolism rate increased significantly from (1.69 +/- 0.36) mlO2/(g x h) to (2.40 +/- 0.09) mlO2/(g x h), compared with the control group( P < 0.05). Sleep deprivation also resulted significantly lower serum thyroxine levels in comparison with the control, serum free triiodothyronine (FT3) level reduced from (3.38 +/- 0.88) pmol/L to (2.38 +/- 0.83) pmol/L, then free thyroxine(FT4) decreased from (14.62 +/- 3.62) pmol/L to (8.26 +/- 2.80) pmol/L (P < 0.05).

CONCLUSIONRapid eye movement sleep deprivation can change energy metabolism remarkable, as well as the alteration of FT3, FT4 levels in serum.
